RAILWAY-CAR TRANSOM AND OTHER WINDOW SCREEN.

Specification of Letters Patent.

Patented March 10, 1908.

Application filed November 12, 1906. Serial No. 342,957.

T 0 all whom it may concern:

Be it known that I, CLARENCE JOHN Mo- NITT, a citizen of the UnitedStates, residing at Salt Lake City, in the county of Salt Lake and Stateof Utah, have invented a new and useful Door, Window, and TransomScreen, of which the following is a specification.

My invention relates to improvements in door, window and transom screensand especially when such appliances are used on railway equipment; andthe object of my improvements are I. To provide a screen that willintercept particles of dust and cinders.

II. To provide a screen that will allow the intercepted particles ofdust and cinders to fall without the opening in which said screen isplaced.

I attain these objects by the device illustrated in the accompanyingdrawings in which as designed for a railway car window screen Figure Iis a front elevation; Fig. II a perspective view from below and Fig. IIIa bottom elevation Similar letters refer to similar parts throughout theseveral views.

(a) is the wooden framework.

(b) is the rubber tongue to make a snug fit in the opening.

(a) is the opening formed in the outer section of frame by cutting awaythe wood so as to continue the space between the outer screen ((1) andthe inner screen (6).

The wooden frame (a) is composed of and put together in two sections, anouter and an inner, as if two separate frames were fastened togetherface to face after screen (d) has been fastened to the outer section andanother screen (e) to the inner section in such a way as to allow aspace of about one half inch to remain between the two screens. Thisspace between the two screens is continued down to the bottom of thescreen (a) through the opening or escapement (0) through whichintercepted particles of dust and cinders may fall outside and away fromthe opening in which screen is placed. In other words, the constructionof the invention may be described to be such that the lower end of theframe is formed with a downward passage coincident with the spacebetween the inner and outer screens, and extending outwardly by reasonof the cutting away of the lower edge portion of the outer section ofthe frame as shown in'Fig. 1. When in operative position, therefore,the'device rests upon the lower end of the inner section of the frame,the lower end of the outer section, nearly throughout its transverseextent, being spaced from the support upon which the de vice may rest.The outer screen (d) stops violence of the motion of said cinders anddust as the particles pass through the meshes of outside screen (d) ofwire or other material and hence they do not retain suflicient momentumto pass through the meshes of the inner screen (a), but are interceptedby same and fall downward and out of the screen through the opening (0)in the bottom of the frame.

What I claim as my invention and desire to secure by Letters Patentis- 1. In means of the class described, the combination of a frame,inner and outer screens applied thereto in spaced relation, the outerportion of the frame being cut away at its lower edge to form a passagetransversely of the frame, said passage com municating with a secondpassage leading downwardly from the space between the inner and outerscreens.

2. In means of the class described, the combination of a frame, innerand outer screens applied thereto in spaced relation, there beingprovided a passage extending downwardly through the lower end of theframe coincident with the space between the screens, and thenceextending outwardly through said lower end to the outer side of theframe.

3. In means of the class described, aframe composed of inner and outersections secured together, screens applied to the frame in spacedrelation to one another, the lower end of the outer section of the framebeing formed with a downwardly extending passage or opening coincidentwith the space between the screens, and having its lower edge cut awayto provide a continuation of said passage to the outer side of thedevice, whereby foreign substances passing to the space between thescreens may have lateral exit at the lower end of the frame.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CLARENCE JOHN MCNITT.
